Gene,
You could do that also, but it's depends on the diameter of the
rolls and the diameter your rolling your piece into. If your rolls aren't
to large, and what your making is big and flexible, you can lift what was
the first end already through the roles and have it not pass through
again. It's difficult to explain.
You can't send an overlap through the roles, so if you leave your
stock longer then you need for the finished tube your making, you have to be
able to lift what was the leading edge up as it comes around so
it passes above the top role leaving the last of the material to finish going
through the roles. If your roles are big, what your rolling is small
in diameter, or your material is thick and not flexible, it's tough to do it
that way. In the worse case, you can make two (more then
half) shells and cut off the non round part.
Or have roles like I described to Rick and back feed the material.
